Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to an intelligent maintenance device for large-volume concrete. Background Art

[0002] After pouring large-volume concrete, hydration heat will be generated due to cement hydration. The heat loss rate inside the concrete is lower than the heat loss rate on the surface, resulting in a large temperature difference between the inside and outside. The temperature stress generated will cause cracking of the large-volume concrete. Therefore, when curing large-volume concrete, it is usually necessary to control the temperature difference between the inside and outside within a set range by cooling the inside and outside simultaneously. At present, the method of cooling the inside of large-volume concrete is generally to lay pipes inside the concrete and to achieve the purpose of cooling by introducing cooling water into the pipes. However, the existing connector between the pipe and the external water pipe has a single structure and mainly relies on a threaded connection to achieve sealing, resulting in poor sealing effect and prone to water leakage. To this end, the inventor proposed an intelligent curing device for large-volume concrete. Utility Model Content

[0034] Example 1

[0035] See also Figure 1-Figure 3 This embodiment provides a large-volume concrete intelligent curing device to solve the problem of poor connection sealing between the internal pipeline and the external water pipe of the existing concrete curing device due to the use of a single threaded connection method.

[0036] In this embodiment, the intelligent maintenance device for large-volume concrete includes a pipe 20 laid inside the large-volume concrete 10 and connected to a water tank 30 to form a loop. The water tank 30 is also connected to a spray mechanism 40. Both ends of the pipe 20 are connected to a water pipe 31 arranged on the water tank 30 through a connector 50. The connector 50 includes a coaxially arranged outer cylinder 51 and an inner cylinder 52. The outer cylinder 51 has an internal thread. The inner cylinder 52 is rotatably clamped to the inside of the outer cylinder 51. Sealing rings 53 are provided on the outer walls at both ends of the inner cylinder 52. An installation space is formed between the inner cylinder 52 and the outer cylinder 51.

[0037] In this embodiment, the pipeline 20 and the water pipe 31 are connected by the outer cylinder 51, and the inner cylinder 52 moves synchronously along the axis following the outer cylinder 51, and a sealed connection with the pipeline 20 and the water pipe 31 is achieved through the sealing ring 53. The double seal is used to improve the sealing performance of the connection between the pipeline 20 and the water pipe 31, which has the advantage of easy disassembly and assembly.

[0038] It should be noted that an internal sensor 11 is provided inside the mass concrete 10 for monitoring the internal temperature, an external sensor 12 is provided on the outer wall of the mass concrete 10 for monitoring the surface temperature, a first water pump (not shown in the figure) for supplying water to the pipe 20 and a second water pump (not shown in the figure) for supplying water to the spray mechanism 40 are provided inside the water tank 30, and the cooling water inside the water tank 30 is distributed and supplied to the pipe 20 and the spray mechanism 40 to achieve simultaneous cooling and curing of the inside and outside of the mass concrete 10. According to the temperature feedback from the internal sensor 11 and the external sensor 12, the working state of the water supply of the first water pump and the second water pump can be adjusted to make the temperature difference between the inside and outside of the mass concrete 10 within the set range, so as to prevent cracking due to the large temperature difference between the inside and outside.

[0039] In addition, the connector 50 includes an outer cylinder 51 and an inner cylinder 52. The inner cylinder 52 is integrally inserted into the interior of the outer cylinder 51 and is coaxially arranged with the outer cylinder 51. A snap ring 511 is integrally formed on the inner wall of the outer cylinder 51, and the plane where the snap ring 511 is located is perpendicular to the axis of the outer cylinder 51. The snap ring 511 is coaxially arranged with the outer cylinder 51, and the snap ring 511 is integrally arranged at the middle position of the outer cylinder 51 along the axial direction. A snap groove 521 for snapping the snap ring 511 is provided on the outer wall of the inner cylinder 52, and the snap groove 521 is coaxially arranged with the inner cylinder 52, and the bottom of the snap groove 521 abuts against the inner circumferential surface of the snap ring 511. The sealing ring 53 is fixed to the outside of the inner cylinder 52, and the sealing ring 53 is coaxially arranged with the inner cylinder 52. As an example, two sealing rings 53 are arranged at intervals along the axial direction at each end of the inner cylinder 52, and the sealing rings 53 are symmetrically arranged at both ends of the inner cylinder 52 as a whole.

[0040] When in use, first screw the connector 50 onto the pipe 20. Specifically, the inner wall of the outer cylinder 51 is threadedly connected to the outer wall of the pipe 20, the inner cylinder 52 is inserted into the pipe 20, and the sealing ring 53 is squeezed between the outer wall of the inner cylinder 52 and the inner wall of the pipe 20; then screw the connector 50 as a whole toward the water pipe 30 until the outer cylinder 51 is threadedly connected to the outer wall of the water pipe 31, and the sealing ring 53 on the other end of the inner cylinder 52 is squeezed between the outer wall of the inner cylinder 52 and the inner wall of the water pipe 31. The outer cylinder 51 is threadedly connected to the pipe 20 and the water pipe 31 at the same time, and the sealing rings 53 at both ends of the inner cylinder 52 are respectively sealed and connected to the pipe 20 and the water pipe 31. The sealing effect of the threaded connection and the sealing effect of the sealing ring are improved.
